OPERATING MANUAL
Thank you for purchasing an Oriental Motor product.
This Operating Manual describes product handling procedures and safety
precautions.
• Please read it thoroughly to ensure safe operation.
• Always keep the manual where it is readily available.
World KSeries Terminal Box Type
Induction Motors and Reversible Motors
•Assign qualied personnel the task of installing, wiring, operating/ controlling,
inspecting and troubleshooting the product. Failure to do so may result in
re, electric shock or injury.
•Do not transport, install the product, perform connections or inspections
when the power is on. Always turn the power o before carrying out these
operations. Failure to do so may result in electric shock.
•Turn o the power in the event the overheat protection device (thermal
protector) is triggered. Failure to do so may result in injury or damage to
equipment, since the motor will start abruptly when the overheat protection
device (thermal protector) is automatically reset.
•The motor is ClassⅠequipment. Install the motor so as to avoid contact with
hands, or ground it to prevent the risk of electric shock. If the motor has a
protective ground terminal, be sure to connect the terminal to the ground.
Dieser Motor ist in Geräten mit Schutzklasse I zu verwenden. Der Motor ist
so einzusetzen, dass er nicht berührt werden kann, bzw. er ist zu erden, um
Stromschläge zu verhindern. Wenn der Motor über eine Schutzerdungsklemme
verfügt, ist die Erdung über diese vorzunehmen.
•Install the motor in an enclosures in order to prevent electric shock or injury.
•Keep the input-power voltage within the specication to avoid re and
electric shock.
•Connect the cables securely according to the wiring diagram in order to
prevent re and electric shock.
•Do not forcibly bend, pull or pinch the lead wires. Doing so may result in re
and electric shock.
•Be sure to insulate the connection terminal of the capacitor. Failure to do so
may result in electric shock.
•Turn o the power in the event of a power failure, or the motor will suddenly
start when the power is restored and may cause injury or damage to equipment.
•Do not touch the connection terminal of the capacitor immediately after the
power is turned o (for a period of 30 seconds). The residual voltage may
cause electric shock.
•Do not disassemble or modify the motor. This may cause electric shock or injury.
CAUTION
•Do not use the motor beyond its specications, or electric shock, injury or
damage to equipment may result.
•Do not touch the motor during operation or immediately after stopping. The
surface is hot and may cause a burn.
•Do not hold the motor output shaft. This may cause injury.
•Keep the area around the motor free of combustible materials in order to
prevent re or a burn.
•To prevent the risk of damage to equipment, leave nothing around the motor
that would obstruct ventilation.
•To prevent bodily injury, do not touch the rotating parts (output shaft, cooling
fan) of the motor during operation.
•When an abnormality is noted, turn o the power immediately, or re, electric
shock or injury may occur.
•The motor’s surface temperature may exceed 70 °C, even
under normal operating conditions. If a motor is accessible
during operation, post the warning label shown in the gure
in a conspicuous position to prevent the risk of burns. Warning label
•Dispose the product correctly in accordance with laws and regulations, or
instructions of local governments.

■How to install the motor
zRound shaft type (6 W)
Drill holes on the mounting plate
and x the motor on the plate
using screws, nuts, and washers
(not supplied). Be careful there
is no gap between the motor
installation surface and the
bracket.
Nominal diameter of screw: M4
Tightening torque: 2.0 N·m
(17.7 lb-in)

Mounting screws
Mounting plate
Nuts
Washers
Note
Do not insert the motor into the mounting hole at an angle or force it in, as
this may scratch the ange pilot section and damage the motor.
zPinion shaft type
Drill holes on the mounting plate
and x the motor and gearhead
on the plate using screws supplied
with the gearhead. Be careful
there is no gap between the
motor ange and the gearhead.

Note
Use the gearhead with pinion shaft which is identical with one of motor.
zMotor with cooling fan
When installing a motor with cooling fan onto a device, leave 10 mm
(0.39 in.) or more behind the fan cover or open a ventilation hole so that the
cooling inlet on the back of the motor cover is not blocked.
■Mounting the capacitor (Only for single-phase motors)
Before mounting the provided capacitor, check that
the capacitor’s capacitance matches that stated on
the motor’s name plate. Mount the capacitor securely
by using M4 screws (not provided).
Ø4.3 mm
(Ø0.169 in.)
Note
•Do not let the screw fastening torque exceed 1 N•m (8.8 lb-in) to prevent
damage to the mounting foot.
•Mount capacitor at least 10 cm (3.94 in.) away from the motor. If it is located
closer, the life of the capacitor will be shortened.
Connection and operation
Insulate all the wire connections, such as the connection between the motor
and the capacitor connection. Use the supplied capacitor cap to insulate the
capacitor terminal connection.
Note
•Insulation class of this motor is B.
Make sure that the motor case temperature does not exceed 90 °C (194°F)
during operation of the motor. Operation exceeding case temperature
90°C (194 °F) may signicantly deteriorate the coils and ball bearings of
the motor and shorten the motor’s life span. Motor case temperature can
be measured by xing a thermometer on the motor surface. It can also be
measured using thermo tape or a thermocouple.
•To change rotation direction of the single-phase induction motor, wait
until the motor completely stops. Otherwise its direction may not change
or may take much time to change.
•Single-phase motors use a capacitor and keep it connected even after
rotation of the motor has started.

•When sealing the terminal cover, ensure that no scraps or particles get caught
between the contact surfaces.
•In order to maintain a tight seal around the terminal box, the rubber seat use
between terminal box cover and terminal plinth. Also this terminal box is
constructed to hold a rubber seat. If this rubber comes out of the box, please
seat it correctly on the box.

•Also refer to the tightening torque table to determine the appropriate
tightening torque to use when fastening the terminal box cover and terminal
block.
Terminal box cover 0.3 Nm (42 oz-in.)
Motor connecting terminals 0.8 to 1.0 Nm (113 to 142 oz-in.)

•Cable entry is possible at any of the four sides of the terminal box. Undo the
screws which xed terminal box to the motor case, position the terminal box
so that the outlet faces in the desired direction and re fasten the screws.

•When sealing the terminal cover, ensure that no scraps or particles get caught
between the contact surfaces.
•The terminal cover screws are specically designed for mounting the terminal
cover. They are provided with a rubber seal and metal washer that keep the
terminal box splashproof. In order to maintain a tight seal around the terminal
box, use only the provided screws. Also, this terminal box is constructed to hold
a gasket. If this gasket comes out of the box, please reseal it correctly on the box.
Also refer to the tightening torque table to determine the appropriate tightening
torque to use when fastening the terminal box cover and cable outlet.

Note
•To make shielding function fully eective, use a cable of an appropriate
diameter.
•Securely ax the cable exposed outside the motor so that it does not
receive stress.

Locked rotor burnout protection
This motor is equipped with one of two methods to prevent burning the motor
as a result of abnormal heating.
■Thermal protection
“TP” is stamped on the motor nameplate. The motor has an“auto reset”
type thermal protector built into its motor coil. When the motor reaches a
predetermined temperature, the internal thermal protector is activated and the
motor is stopped.
Always turn the power o before performing inspections.
Thermal protector activation range:
Power is turned o at 130±5 °C (266±9 °F)
Power is turned back on at 85±20°C (185±36 °F)
■Impedance protection
“ZP” is stamped on the motor nameplate. The motor has higher coil impedance.
When the motor goes into locked rotor condition due to a malfunction, coil
impedance rises, suppressing input power to the motor and protecting the
motor coil from burnout.
Troubleshooting
When the motor cannot be operated correctly, refer to the contents provided
in this section and take appropriate action. If the problem persists, contact your
nearest oce.
